An outer'valve sleeve 24 is arrangedtoslid'eon the inner'valve' sleeve 2l and is provided with ports 25 which areadapted to align'with-'thel ports 23 when the outer valve sleeve 24 isin its upper position.

A pin 26 is secured to theshoulder 22 ofthe inner sleeve 2l andprojectsdownwardly through a recess 21 formed through the shoulder- 28' "at thelower end of the outer valve sleeve 2'4'. The purpose of this pin 26. isto prevent relative rotation between the valve sleeve 2`I` and' 24.Threadedly connected` to the shoulder onthe outer valve sleeve 24 is thespring housingl 29 which encircles the tubular guide. Z't'o deii'nel anannular recess 30. A compression spring' 3l' "is positioned within thisyannular recessk 305 and is confined between the shoulder 22' on theinner valve sleeve 2l and theA shoulder '32 at the-lower end ofthespring housing 23.

Threadedly secured. to the lower end of 4the spring housing 2'9 is thevent pipe 33 and at the lower end of the vent pipe 33, the hollowextension rod-34 `is secured and fastened by means. of the locknut 35.At the lower end of the hollow rod` 34Y is a circular flexible disc 36'.A screw 31 and washer 38 are used in securing the disc 36 to the lowerend of the hollow rod. 34. The disc is made exible for several' reasonsvas will appear hereinafter and in order that itlmay be inserted throughthe restricted outlet I3 and neck H of the container. ID.

A hollow cup element 33 is. secured to the hol.- low rod 34 by means ofthe nut 40 and acts Las astiifener element supporting the flexible.vdisc 35.

Means are provided for actuating. the valve sleeve 24 to bring the valveports 23land 25 into alignment, and as illustratedsuch means include a`bifurcated post 4l securedv on ther cap I8 'andl carrying a pin 42 forpivotally supporting an actuating crank 43. A .thumb pad ifi isprovidedon one end of the crank 63 and atlthe other end the crank i3 ispivotally connected to an actuating rod 5- W-hich extends downwardlythrough the opening 45 .at the upper end of the cap kI8 and throughv thetubular guide 2li.. The Ilower endoi the actuating `rod 45 is threadedlyreceived in a dam element 33a threaded into. the vent pipe '33.

From the above description it will be: understood that when theactuating crank wismoved from its normal position, indicated by lthedotted lines in -ligiire 1,.,to'thgimsition indian-ted by' the fsolid.linesQthctmd 4E, together 4witlfl the vent' pipe l33, spring housing 2B,and cuter valt/Te sleeve 24, is iii'ftcd vertically. .liftizigmotion thehollow rod t4. passage terminates in vent ports e drilled laterally intothe lower end of the hollow rod 34. .The ports E@ lead into an annularspace within ports 5i) into the annular space 5I.

brings the ports 25 from their inoperative position to their position ofalignment with the ports 23, thereby establishing a flow path from theinterior of the neck II to the discharge port I9. The same liftingaction by the rod 45 serves to lift the hollow rod 34 secured on thelower end of the vent pipe 33 and thus bring the flexible disc 36 fromits normal inoperative position, as indicated by the dotted lines inFigure 1, to its operative position indicated by the full lines.

In its operative position the flexible disc 36 contacts the inside ofthe container Ii) to form a seal and to dene a measuring chamber 41within the neck II of the container I!! and between the disc 3S and theupper end of the stationary body I4. When the container is inverted fromthe position shown in Figure 1 and when the thumb pad 44 is actuated tobring the valve ports and 23 into alignment, the disc 3e preventsladditional now of fluid from the interior of the container ii) into thechamber 4i within the neck portion i i sc that only the fluid within.the chamber 41 is discharged through the port IS.

Means are provided for venting the chamber 41 during the in erval ofdischarge therefrom in order to bring air into the neck of the containerand thus facilitate discharge through the port IS.

`As shown in the drawings, this vent means includes the opening 4 in theupper end of the cap I8 and the annulus 43 between the actuating rod 45and the tubular guide 2?). The vent passage, which includes the annulus4B, continues downwardly through the vent pipe 33 through the passages43 formed through the dam 33a and into The lower end of this vent thecup member 39. When the iiuid within the chamber 41 is being dischargedthrough the port I9, air from the atmosphere is admitted through thevent passage including the annulus 4S and hollow rod 3E and flowsoutwardly through the Since the pressure of the uid within the chamberil adjacent the disc 3B is somewhat below atmospheric pressure duringthe interval of discharge, the air admitted into the space 5i escapesradially outwardly past the flexible disc 36 and into the chamber 41.The discharge of fluid through the port I9 is therefore rapid andefficient.

When the measuring valve assembly is initially vinserted into the neckof container lli, the flexible disc 35 cooperates with the rim on thecup memy, ber 3S to prevent entry of liquid into the annular space 5 I,and hence no liquid enters the vent passage. When the container isinverted, the chamber 41 lls with liquid, but the seal between theflexible disc 35 and the cup member 3S again prevents entry of liquidinto the vent space 5l.

`Actuation of the thumb pad however, serves Hto flex the` disc 36against the inside of the conn ltainer wall and thereby materiallydiminish the Lsealing eiect between the flexible disc and the cup memberfpartially destroyed, the air within the annulus instantly available attime of discharge to enter 'i the chamber c1 and hence to promotenonturbu- 'lent ow of liquid from the discharge orifice I.

While the container I0 is held inverted in pouring position a number ofsmall glasses may be lled, discharging the same amount of liquid intoeach glass. It is not necessary to re-invert the container in order tofill each glass. When the liquid in the chamber 41 has been dischargedinto the first glass, the thumb pad 43 is released to permit the spring3| to close the ports 25 and 23 and then to move the exible disc 36 outof contact with the inside of the container I0. The air in the chamber41 which entered through the vent passage is then displaced by uidentering the chamber 41 from the main part of the container I9. The disc36 and rim on the cup element 39 cooperate to prevent entry of uid intothe'vent passage while the chamber 41 is filling.

In order to change the volume of fluid contained within the measuringchamber 41, a displacement element 52 may be provided which is receivedon the rod 34. The displacement element 52 is formed of a size todisplace the proper amount of fluid, and if necessary may extendupwardly to cover all or a portion of the spring housing 29, as well asthe rod 34, as will be readily understood.

Having fully described my invention, it is to be understood that I donot wishto be limited to the details herein set forth, but my inventionis of the full scope of the appended claims.

I claim:
